See life in the best light with lenses that
automatically adjust from clear to dark and every shade in between
according to light conditions. Graphite green perfectly complements many
frame styles and colors. From classic to cutting-edge style, you can
transform any pair of regular eyeglasses into a striking look all your
own!

Photochromic molecules adjust to
light

When Transitions® lenses are exposed to UV light, trillions of
photochromic molecules in the lenses begin to change structure.
This reaction is what causes the lenses to darken. Only Transitions®
Signature™ lenses use exclusive Chromea7™ technology, a new
formulation that allows the lenses to be more responsive than ever
before.

More reactive to indirect light

Chromea7
technology was designed to be even more reactive to indirect
light. Indirect light can come from many sources such as light
bouncing off buildings, cars, or other surfaces or light
filtering through trees or clouds. The lenses can sense this
light, even when you’re facing away from it, and adjust to the
appropriate shade for your situation.

More responsive in hotter
climates

Temperature influences the molecules in
photochromic lenses; they don't get as dark in hot climates as
they would in colder weather because of how heat interacts with
the molecules. The molecules in Chromea7 technology were
structured to be more independent of temperature, which means
they get darker in hotter climates.

Just the right shade,
just the right color

In other photochromic
lenses, wearers have noticed colour variations as the lenses
tint and react to different types of light. The dyes in
Transitions® lenses and in Chromea7 technology work together to
provide an even colour at all levels of tint, in both grey and
brown options.

Revolutionary testing for
a revolutionary product

People wear their lenses
all day, every day, in a variety of locations, temperatures and
weather conditions. They experience sunny conditions, cloudy
conditions and everything in between. Their position in relation
to the sun also changes quite a bit. We took all of these
factors into account when we tested Chromea7 technology in over
200 real life conditions representing over 1,000 scenarios that
wearers experience around the world. We call it Life360™.
